Researchers See What Memory Looks Like in Brain (w/pic)

Biologists led by Dr Don Arnold and Dr Richard Roberts from the University of Southern California, Los Angeles, have released an astonishing picture of memories forming inside the mouse brain.

The researchers engineered microscopic probes that light up synapses in a living neuron in real time by attaching fluorescent markers onto synaptic proteins. The fluorescent markers allow them to see live excitatory and inhibitory synapses for the first time and, importantly, how they change as new memories are formed. The findings are published in the journal Neuron.

The synapses appear as bright spots along dendrites. As the brain processes new information, those bright spots change, visually indicating how synaptic structures in the brain have been altered by the new data.

“When you make a memory or learn something, there’s a physical change in the brain. It turns out that the thing that gets changed is the distribution of synaptic connections,” Dr Arnold explained.
